Youtube Comment Bot is an automation software tool used for bulk commenting on youtube videos, it allows users to automatically post mass comments and upvote/downvote (Like/Dislike) on YouTube videos that match set keywords for your niche, with your chosen marketing message for your brand or product using multiple accounts.

You will need private proxies to run with this bot. You can buy proxies from here.

BuyProxies is tested and working perfect for Youtube and other social accounts. I always use this service for Google accounts and doing bulk upvote/like.
